[EVO 4G General] koolhwhip:
I just came across this realization last night, and it is very, very disconcerting - to say the least.

I have had my EVO since day one launch - no problems with it. I am not rooted, and have the latest OTA update applied.

I actually have the two Transformers moves from the HD2 on my memory card from a friend, as well as a couple more he ripped/formatted for our phones (he now has an EVO as well). The night before last I was bored/tired and stayed up in bed watching parts of both films. One day later (last night) I was out with friends and one of them asked me to show another how good the video looks on our phones. I fired up Meridian (what I always use to watch movies on the EVO) and was shocked to find the two TF films were nowhere to be found. What's more, the listing of "VIDEO00__" files from the EVO camcorder seemed suspiciously short - like some of those were missing, too. Now, I know that at least the TF films were on there the night before.

I got home, removed the card from the phone and fired it up on my laptop. I used two file recovery programs: Recuva and Pandora Recovery (both free) to analyze the card. I found the Transformers files as if they'd been deleted. I also found a whole host of other files that have been deleted. The vast majority of them seemed to be media of some sort, from photos to Video files (taken with the phone). Since most of the media produced from the phone are "IMAG00__.jpg" or "VIDEO00__.3gp" and I DO manually delete some of them time to time, it was hard to tell what was intentionally deleted and what wasn't. HOWEVER, there were definitely media files I would NOT have deleted, like pictures from my Wallpapers folders, photos from other folders I manually renamed based on the content, etc.

I don't know how long this has been going on - I know that the file recovery program Recuva tell you what file overwrote another. Using that, I could see that a movie I would not have deleted (Iron Man) was overwritten with a photo taken with the phone that, based on the file number, was taken on or about July 4th. Flipping through my video gallery, I am certain I am missing many of those, too, as videos from a certain event (family gathering) that I know I had a handful of files for now only have one.

I've had the phone now for basically a month and a half - and while I am normally good about backing up here and there I have neglected to do so often with my EVO as I've been very busy (getting married in about a month) and I didn't think I'd need to have a backup short of physically losing the phone (have never lost a phone). This realization scares the heck out of me, and I'm wondering if anyone has experienced it or has any ideas about it. Until last night when I happened to be looking for a specific file(s) I used the night before, I didn't have any idea this was happening.

If it helps, in between the night when I watched the movies that later went missing and the night I realized they were gone I connected my EVO to the computer via USB to transfer a file and charge it. I realized recently whenever I connected the phone the computer would automatically read/access the card without me ever having to choose the option from the pull down menu. I thought that maybe that kind of activity could be the root cause of missing files (you know how flash drives don't like to be fiddled with while reading/writing). I did some searching before starting this post and found out that behavior is caused by a setting in DoubleTwist which I have since changed. Still, I have a hard time believing that's the root cause of files which just seem to be deleted without me ever doing it.

Any thoughts or ideas? Any way you members can check to see if you seem to be missing any media (or other) files?
